Not really a Gallows fan but there's this film called 'Lives of the Artists' which follows one snowboarder, a couple of surfers and one band (Gallows)for a year. Found out about it because of the snowboarding aspect and I feel that I should warn you that it is heavily sponsored by an energy drinks company, so its bound to 'aspire to their brand values' and shit like that. Snowboarders and surfers are always doing films like this but I'm not sure how dignified it is for a band like Gallows to cosy up to the man.

Anyway, here's the link: http://mpora.com/livesoftheartists
